AptCacherNg Docker container image

This container image allows to dockerize AptCacherNg, making your Debian-based containers to use the AptCacherNg proxy for both building and running containers. In the best of cases, it will greatly speed up the package installing process on scenarios with large ammount of packages.

Usage

Starting AptCacherNg

Start AptCacherNg container, using a dedicated network

docker run -d -p 3142:3142 --name apt-cacher-ng -v $(pwd)/cache:/var/cache/apt-cacher-ng amitie10g/apt-cacher-ng

Building your container

Before get started, add this at the top of the Dockerfile step context, in order to instruct apt to use your proxy:

ARG APT_PROXY
RUN if [ ! -z "$APT_PROXY" ]; then echo "Acquire::http { Proxy \"http://$APT_PROXY:3142\"; };" >> /etc/apt/apt.conf.d/01proxy; fi

And add this at the bottom of the step, in order to remove the proxy from the final image:

rm /etc/apt/apt.conf.d/01proxy

Then, build your container:

docker build -v APT_CACHE=$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' apt-cacher-ng) -t <your container:tag> .

Running your container

docker run --network=mynetwork -v APT_CACHE=$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' aptcacherng) <your container:tag>  <commands>
